------------------------------------------------------------------
I think the problem is inside function Wicket.Event.fix (file
wiket-evet-jquery.js, line 124). Here we should replace 'jQuery.event.fix(evt)'
with 'jQuery.event.fix(evt || window.event)'.
PS: for those (like me) who aren't black belt of JavaScript, it is worth
remembering that OR operator can be used also to express an alternative value
if a variable is undefined.
